THE PURSUIT OF HAPPINESS 


by Tom Briant 


Tired of playing Bug tot on your XE65 gaae systea? Check out 
Ron Hiller's 2 guick, fun 8-bit type-in prograas! Also check out 
the want ads! The gentlesan selling the Indus drives hasn't sold 
out on the 8-bit; he's buying a 8-bit hard drive! Do yourself and 
hia a favor and call guick. 

I aentioned Neotron Inc.'s NorriUp aultiple font word processor 
last aonth. I haven't seen it on the shelf yet; but its coapanion 
prograa, Fontz, is available now. It converts Hac, Degas, and 
HippoHord fonts into GO! fonts. This should expand the options for 
EasyDraw and HS Nrite users. 

I also aentioned Eidersoft's Quantua Paintbox last aonth, too. 

I feared it would sacrifice the clear Atari display in order to get 
4,096 colors on screen. I saw it at the ST workshop on Harch 3d and 
the display looked sharp and clean. Hove over, Aaiga! 

Before I go further, let ae point out this aonth's cover coaes 
froa both the ST and 8-bit. Rick DeHaven scanned soae back issues 
with the Navarone scanner he desonstrated last aonth, cleaned up the 
iaage with Degas Elite and laser printed the cover with Easy Draw . 
Rem Hiller created the cover art with BASIC on his TO. Don't hide 
your talent! If you've got a siaple prograa that generates 
interesting pictures, share it with us! Strut your stuff!!! 

I reviewed 3 new ST products this issue; Qmi-Res, Universal 
File Selector, and a RGB to coaposite aono convertor. If you bought 
a hot product recently, tell us about it! I hope to get a review of 
Quantua Paintbox for the next issue; but what if the last piece of 
software you purchased was last aonth's Disk of the Honth? Great, 
who's been using R-Draw? Hhat about Unitera 2.0? You 8-bit owners 
out there, ail those new XE65 owers and their parents will want to 
buy word processors soon to do book reports. Which ones (to you 
recoaaend, both P/D and Coaaercial? And how do they hook up a 
printer to the XE65? 

With tax tiae approaching, you aight want a spreadsheet; but you 
can't see paying $60 to $ZK) for software you eight only use Airing 
tax season. In SI6 8 of the ST-BBS, you will find VISICALC.ARC aid 
SET.ARC, two shareware spreadsheets. Try the* out and let's have 
BATHE OF THE SPREADSHEETS, just like they do in FC-Hagazine . 

Finally, you, the aeabers of S.D.A.C.E., have an invitation 
froa the NORTH ORANGE COUHTY CQHPUTER CLUB to attend their 19th 
annual Coaputer Swap Heet at Fullerton College on Sunday, April 
24th, 1988 froa 8 A.H. to 2 P.H. Contact ae for further details aid 
those all iaportant seller application foras.

LOW-COST ST VIDEO & GEM OPTIONS 


BY 

Thomas Briant 


Until no*, taiga oners had sore video output options than ST oners 
did. With an ST, you used the Atari aonitors. IT you bought a 520 
with an RF wdulator, you could buy a oaposite cable. 
Enterprising, affluent oners have developed switchboxes allowing 
MultiSync aonitors to run all 3 resolutions beautifully. Now tau- 
Res software ($34,951 fro« Hypertek/Silicon Springs and E. Arthur 
Brown's 1040 Composite Cable ($24,951 give the rest of us additional 
options, too. 

Omi-Res is 9 programs in an AUTO folder. Upoi bootup, the RENAME 
prograe lets you select I of the 8 Osii-Res programs, allowing you 
to run color prograas on a high resolution sonitor. Option 1 gives 
you a black and white display, 1/4 screen display in low resolution 
or 1/2 screen in aediua resolution. Optical 2 gives 4 gray scales to 
represent colors, a 1/2 screen display in It* and full screen in 
aediua, and slower screen displays. Option 3 gives 16 gray scales, 
full display in It* and aediua, and the slowest screen updates. 
Kith 1 aeg or acre of aeaory, you can use Option 4, a faster version 
of Option 3. Options 5-8 work like 1-4, but reset the color palette 
when the prograa finishes. 

For you color aonitor owners, Options 1-3 allow you to run hi$i- 
resolution prograas an color aonitors. Upon bootup, you get a 
scaled down desktop. Press Shift-Alt-Help aid get the desktop's top 
half. Press 9iift-Alt-Help again and get the bottoa half. Press 
aift-Alt-Help a fourth tiae and you can scroll the screen up and 
down. You should know that Hypertek considers this a tricky aode at 
present. 

You can’t deny Oani-Res's convenience; but if you have a composite 
aonitor on hand, you can use E. Arthur Brown's 1040 Coaposite Cable. 
This cable, which they just brought out as itea 1127-222 for $24.95, 
turns It* aid aediua resolution RGB color froa any ST into 16 gray 
scale coaposite aonodiroae. Eidersoft Karate supposedly plays 
beautifully with "asazing sharp detail and subtle gray 
shading...while playing pefectly noraal in every other aspect." 
(Look, it's only $24.95 and who knows when Practical Solutions will 
bring ait their full-color RS5-to-coaposite box? This newsletter 
goes to Arizona; I invite angry retorts froa thea.) 

These products widen the ST’s video options without spending a 
fortune a 1 risking the hardware. Yes, they work with both sets of 
ROM's, too. If you use both to run high-resolution prograas on a 
cheap coaposite aonitor, leave a note on the BBS on how it looks.

UNIVERSAL ITEM SELECTOR 

The f$M itea selector is very handy as it coaes. You don't have 
to reaeaber haw deeply you buried your prograa and just what you 
naaed all those folders/subdirectories that you put it in. Still, 
wouldn't you like your file selector to scroll tie iteas up and down 
to begin with? Many prograas will do this already; but all too aany 
don’t. And haw about the ability to foraat soae disks, especially 
if you can't access the aenu bar in this prograa, just the itea 
selector? UNIVERSAL ITEM SELECTOR ($15.95) solves those probleas 
and adds the ability to COPY, MOVE, RENAME, DELETE, MAKE FOLDERS, 
print out a DIRECTORY, LOCK/ULQCK FILES, HORIZONTALLY SCROLL to see 
the files' size and date, and choose any of the 16 logical drives. 

Of course, no prograa can do it all, aid IKIVERSAL ITEM SELECTOR 
states clearly that that you will experience trouble with Hichtron's 
ALT, EASEL/ST froa Coaputer Fenestrations when naming T0S/TTP 
prograas; and especially WORDPERFECT, whose own itea selector box 
does a lot of the things UNIVERSAL ITEM SELECTOR does. 

The software coaes in the barest package I've seen in a coaaercial 
product; a plastic heat-sealed bag with the registration card folded 
around the disk. To print out the docuaentation, you can either 
load UNIVERSE.DOC into 1st Word or Word Writer or load the ASCII 
text version, UNIVERSE.ASC, into your favorite word processor/text 
editor. This gives you 9 pages of concise inforaation. They didn't 
copy-protect the disk. Instead, they iabedded the prograa serial 
nuaber in the prograa code and offer to sell original purchasers 
additional copies at $10 a copy. Yes, that's $10, cash or check, 
wrapped in an article or graphic, at the April ST aeeting or aailed 
to tiie S.D.A.C.E. P.0. Box in care of the editor. 

When you see the directory of your disk, you'll see a folder naaed 
"FREE_ACC". Applications 6 Design Software threw in a bonus, a very 
nice f&M-disk/print spooler desk accessory that also loads if to 
ten files. 

I've written a rather bare description of this terrific utility. 
To see aose, get a copy of the deao version froa the ST-BBS. After 
you see the dew, you'll want the real thing, I guarantee.

WHISTLE AND BOMB SOUND 


by 

Ron Miller 

Atari computers have some nice sound generation capabilities. 
Sound generation programs tend to be short and they make fun 
experiments. The kids have lots of fun with the sounds so here 
is a short one the kids can play with. This particular program 
was created by Richard Kruse in Creative Computing . This program 
demonstrates one fact about creating sound on a computer. To 
create complex sounds (bombs, ringing, shooting, dogs barking, 
etc) the computer must have more than one sound generator 
channe1. The fo1 lowing little program uses three sound channe1s 
at once. If you want to experiment with sound, use more than one 
sound channel and change the sound frequencies and volumes 
together.

(Editor’s note: Thanks, Ron, for these two short programs. I 

invite you authors of short type-in programs for both the 8-bit 
and ST to submit them via the BBS, the mailbox, or in person at 
the ST meeting.) 








THE FINAL WORD 


by Mark Lawless 


Well, this month brings a lot of interesting happenings to the 
Atari world. All of the magazines talk doom for Atari. For 
example, many mention piracy and its affect on the computer; 
others talk about Atari and how they are losing the technical 
edge now that IBM has 386 and 286 machines out and the Macintosh 
II adds color to the Mac line. 

Personally, I don’t understand all of the gloom. I have been with 
Atari since the beginning of the ST line and things have never 
been so good. As we all know, a computer is only as good as the 
software, and the software keeps coming. Atari has put out 
Microsoft Write for what it is worth (the jury is still out on 
this one.) WordPerfect has been cleaning up their software to a 
very workable form. 

The hardware has gotten better. The Mega is here; the Laser is 
here; and probably the biggest improvement is the fact that you 
can finally get quality hard disks to run on any system in any 
size and shape. Since the last meeting many people have gotten 
the hard disk bug and shelled out the money for probably the 
single best improvement to their systems. ( I would rather have 1 
meg and a hard disk than 2 megs without!) 

(*' " iX \ 

I wasn’t able to make it to the last meeting but I hear it was a 
success. There seems to be a lot of interest in showing off 
support hardware. I plan to have a printer meeting in the not too 
distant future where people can bring in their fast printers, 
their color printers, print drivers, etc. I think that a lot of 
folks want for those hard to find drivers that some of us are 
holding dear. 


Thanks Mark Lawless / Pres.
